9. Turn the new ServeRAID-8k SAS controller so that the keys on the bottom edge align correctly with the connector. 10. Firmly press the ServeRAID-8k SAS controller straight down into the connector by applying pressure on both ends of the controller simultaneously. The retaining clips snap into the locked position when the controller is firmly seated in the connector. Note: If there is a gap between the controller and the retaining clips, the controller has not been correctly installed. In this case, open the retaining clips and remove the controller; then, reinsert the controller. 11. Remove the battery from the ServeRAID-8k SAS Controller package. 12. Slide the battery mounting tabs into the battery mounting clips on the server wall that is next to the ServeRAID SAS controller connector. 13. Connect the battery to the ServeRAID-8k SAS Controller. 14. Replace the air baffle over the DIMMs (see "Installing the DIMM air baffle" on page 37). 15. Replace the riser-card assembly. If you have other optional devices to install or remove, do so now. Otherwise, go to "Completing the installation" on page 81. Notes: 1. When you restart the server for the first time after you install a ServeRAID-8k SAS controller, the monitor screen remains blank while the controller initializes the battery. This might take a few minutes, after which the startup process continues. This is a one-time occurrence. Important: You must allow the initialization process to be completed. If you do not, the battery pack will not work, and the server might not start. The battery comes partially charged, at 30% or less of capacity. Run the server for 4 to 6 hours to fully charge the controller battery. The LED just above the battery on the controller remains lit until the battery is fully charged. Until the battery is fully charged, the controller firmware sets the controller cache to write-through mode; after the battery is fully charged, the controller firmware re-enables write-back mode. 2. When you restart the server, you will be given the opportunity to import the existing RAID configuration to the new ServeRAID SAS controller. Installing a hard disk drive Locate the documentation that comes with the hard disk drive and follow those instructions in addition to the instructions in this chapter. Important: Do not install a SCSI hard disk drive in this server; install only SAS hard disk drives. The following notes describe the type of hard disk drive that the server supports and other information that you must consider when installing a hard disk drive: v The server 3.5-inch models support six slim 3.5-inch hard disk drives installed on Ultra-Slim hard disk drive trays for 3.5-inch drives. For a list of supported 3.5-inch hard disk drives, see http://www.ibm.com/servers/eserver/serverproven/compat/ us/. Chapter 2. Installing optional devices 47

Turn
the
new
ServeRAID-8k
SAS
controller
so
that
the
keys
on
the
bottom
edge
align
correctly
with
the
connector.
10.
Firmly
press
the
ServeRAID-8k
SAS
controller
straight
down
into
the
connector
by
applying
pressure
on
both
ends
of
the
controller
simultaneously.
The
retaining
clips
snap
into
the
locked
position
when
the
controller
is
firmly
seated
in
the
connector.
Note:
If
there
is
a
gap
between
the
controller
and
the
retaining
clips,
the
controller
has
not
been
correctly
installed.
In
this
case,
open
the
retaining
clips
and
remove
the
controller;
then,
reinsert
the
controller.
11.
Remove
the
battery
from
the
ServeRAID-8k
SAS
Controller
package.
12.
Slide
the
battery
mounting
tabs
into
the
battery
mounting
clips
on
the
server
wall
that
is
next
to
the
ServeRAID
SAS
controller
connector.
13.
Connect
the
battery
to
the
ServeRAID-8k
SAS
Controller.
14.
Replace
the
air
baffle
over
the
DIMMs
(see
“Installing
the
DIMM
air
baffle”
on
page
37).
15.
Replace
the
riser-card
assembly.
If
you
have
other
optional
devices
to
install
or
remove,
do
so
now.
Otherwise,
go
to
“Completing
the
installation”
on
page
81.
Notes:
1.
When
you
restart
the
server
for
the
first
time
after
you
install
a
ServeRAID-8k
SAS
controller,
the
monitor
screen
remains
blank
while
the
controller
initializes
the
battery.
This
might
take
a
few
minutes,
after
which
the
startup
process
continues.
This
is
a
one-time
occurrence.
Important:
You
must
allow
the
initialization
process
to
be
completed.
If
you
do
not,
the
battery
pack
will
not
work,
and
the
server
might
not
start.
The
battery
comes
partially
charged,
at
30%
or
less
of
capacity.
Run
the
server
for
4
to
6
hours
to
fully
charge
the
controller
battery.
The
LED
just
above
the
battery
on
the
controller
remains
lit
until
the
battery
is
fully
charged.
Until
the
battery
is
fully
charged,
the
controller
firmware
sets
the
controller
cache
to
write-through
mode;
after
the
battery
is
fully
charged,
the
controller
firmware
re-enables
write-back
mode.
2.
When
you
restart
the
server,
you
will
be
given
the
opportunity
to
import
the
existing
RAID
configuration
to
the
new
ServeRAID
SAS
controller.
Installing
a
hard
disk
drive
Locate
the
documentation
that
comes
with
the
hard
disk
drive
and
follow
those
instructions
in
addition
to
the
instructions
in
this
chapter.
Important:
Do
not
install
a
SCSI
hard
disk
drive
in
this
server;
install
only
SAS
hard
disk
drives.
The
following
notes
describe
the
type
of
hard
disk
drive
that
the
server
supports
and
other
information
that
you
must
consider
when
installing
a
hard
disk
drive:
v
The
server
3.5-inch
models
support
six
slim
3.5-inch
hard
disk
drives
installed
on
Ultra-Slim
hard
disk
drive
trays
for
3.5-inch
drives.
